Description
Bortkastbar, selvtettende støvpose for støvsuger. Disposable, self-sealing dust bag for vacuum cleaners.
j' j'
Oppfinnelsen vedrorer en stovpose for stbvsugere, hvilken pose The invention relates to a dust bag for vacuum cleaners, which bag
er av den type som er utskiftbar, dvs. som kan kastes når den er full, og som er selvtettende, dvs. vanlig lukket slik at stov o.l. ikke kan falle ut av posen, men som kan åpnes automatisk ved innsetning av f.eks. den rbrformet ende av den vanlige, boyelige slange, som benyttes ved en type av stbvsugere, eller eksempelvis ved innsetning av et rorformet element, som utgjor en del av stovsugerens lokk. is of the type which is replaceable, i.e. which can be thrown away when full, and which is self-sealing, i.e. usually closed so that dust etc. cannot fall out of the bag, but which can be opened automatically by inserting e.g. the tubular end of the usual, bendable hose, which is used with a type of stick vacuum cleaner, or for example when inserting a tube-shaped element, which forms part of the vacuum cleaner's lid.
Nærmere bestemt vedrorer oppfinnelsen en bortkastbar, selvtettende stovpose for stbvsugere, bestående av en skive med et hull for innmating av stpv ojj. lignende, organ for automatisk å lukke hullet og 'en papirpose, festet til den ene side av skiven omkring hullet. More specifically, the invention relates to a disposable, self-sealing dust bag for vacuum cleaners, consisting of a disk with a hole for feeding in dust. similar, means for automatically closing the hole and 'a paper bag, attached to one side of the disk around the hole.
Hensikten med oppfinnelsen er å tilveiebringe en utskiftbar og selvtettende stovpose, som har effektiv virkning men allikevel er billig å'fremstille. The purpose of the invention is to provide a replaceable and self-sealing dust bag, which has an effective effect but is nevertheless cheap to manufacture.
Selvtettende stbvposer som er utskiftbare eller av engangstype er kjent. Det er f.eks. kjent å tilveiebringe en papirstbv - pose som i den åpne ende er festet til en skive, i hvilken er utformet et sirkulært hull, som er lukket av et elastisk membran, der har et lite, sentralt hull. Når den rbrformede ende av slangen eller et annet rbrformet element fores mot membranet inn i hullet i skiven, strekkes membranet og det lille hull blir vesentlig stbrre, slik at den rbrformede ende eller elementet kan kommunisere med det indre av stbvposen. Når den rbrformede ende eller elementet trekkes ut, gjeninntar membranet sin 'normale form og lukker stbvposen. Denne kjente konstruk-sjon har de ulemper at den er nokså kostbar (en engangsstbvpose eller bortkastbar stovpose må være billig) og at den tynne gum-mlhinne, som benyttes som membran, utsettes for slitasje. Det finnes også konstruksjoner som har benyttet ganske kostbare pa-pirposer, f.eks. en dobbelpose, som har indre og ytre sjikt med forskjellig porbsitet, idet det ytre sjikt er tilstrekkelig sterkt til å være selvbærende og det indre sjikt er et primær-filtersjikt med stbrre porbsitet. Self-sealing stbv bags which are replaceable or of the disposable type are known. It is e.g. known to provide a paper stbv - bag which is attached at the open end to a disc, in which is formed a circular hole, which is closed by an elastic membrane, which has a small, central hole. When the tubular end of the hose or another tubular element is fed against the membrane into the hole in the disk, the membrane is stretched and the small hole becomes significantly narrower, so that the tubular end or element can communicate with the interior of the support bag. When the tube-shaped end or element is withdrawn, the membrane resumes its 'normal shape and closes the stbvpouch. This known construction has the disadvantages that it is quite expensive (a disposable dust bag or disposable dust bag must be cheap) and that the thin rubber membrane, which is used as a membrane, is exposed to wear and tear. There are also constructions that have used rather expensive paper bags, e.g. a double bag, which has inner and outer layers with different porosity, the outer layer being sufficiently strong to be self-supporting and the inner layer being a primary filter layer with higher porosity.
Ifblge oppfinnelsen foreslås det en bortkastbar, selvtettende stovpose av ovennevnte slag som kjennetegnes ved at skiven består av to sjikt av kartong eller lignende materiale, at det indre sjikt har to av fjærorgan påvirkede flik- eller klafforganer som mot fjærvirkningen kan bbyes inn i posen og at det ytre sjikt har et sirkulært hull hvis areal er mindre enn flik- eller klafforganenes samlede areal. According to the invention, a disposable, self-sealing dust bag of the above type is proposed, which is characterized by the fact that the disc consists of two layers of cardboard or similar material, that the inner layer has two spring-actuated flap or flap members that can be folded into the bag against the spring action and that the outer layer has a circular hole whose area is smaller than the combined area of the flap or valve organs.
Ifblge et ytterligere trekk består flik- eller klafforganet av to stort sett rektangulære klaffer skåret ut av det indre sjikt med unntagelse av de sider langs hvilke klaffen er bbybar. j According to a further feature, the tab or flap means consists of two largely rectangular flaps cut out of the inner layer, with the exception of the sides along which the flap is openable. j
Fjærorganet er ifblge oppfinnelsen med fordel anbragct mellom According to the invention, the spring element is advantageously applied between
de to kartongsjikt og består :av en U-formet del med. -to frie;, innboyde ender som ligger an mot hver sin'klaff og sbker å fore denne til stengt stilling. the two cardboard layers and consists of a U-shaped part with - two free;, curved ends that rest against each flap and try to guide it to the closed position.
Et utforelseseksempel skal beskrives i detalj under .'henvisning til tegningene. Fig. 1 viser i perspektiv en nesten sammenpresset papirpose ifblge oppfinnelsen. Fig. 2 viser i plan et ytre kartongsjikt, som danner skivens ytre komponent. Fig. 3 viser i plan det indre kartongsjikt, som danner skivens indre komponent og anvendes sammen med sjiktet ifblge fig. 2.. Fig. k viser i plan posens skive og illustrerer det sentrale hull i det ytre kartongsjikt med de to fliker, som er synlige gjennom dette, og stillingen av en trådfjær, som tjener til å presse flikene til stengt stilling. Fig. 5 viser stbvposen sett fra siden og illustrerer dens skive og den platte, sammenpressede papirpose, som av plasshensyn vis-es med en stor del bortskåret. Fig. 6, 7 og 8 viser henholdsvis plan-, side- og enderiss av trådfjæren. An exemplary embodiment shall be described in detail with reference to the drawings. Fig. 1 shows in perspective an almost compressed paper bag according to the invention. Fig. 2 shows in plan an outer cardboard layer, which forms the disc's outer component. Fig. 3 shows in plan the inner cardboard layer, which forms the disc's inner component and is used together with the layer according to fig. 2.. Fig. k shows in plan the disc of the bag and illustrates the central hole in the outer cardboard layer with the two flaps, which are visible through this, and the position of a wire spring, which serves to press the flaps into the closed position. Fig. 5 shows the stbv bag seen from the side and illustrates its disk and the flat, compressed paper bag, which for reasons of space is shown with a large part cut away. Fig. 6, 7 and 8 respectively show plan, side and end views of the wire spring.
j Fig. 1 viser en papirpose ifblge oppfinnelsen. Den er utformet av et enkelt ark av porbst filterpapir, som nedenfor beskrevet. j Fig. 1 shows a paper bag according to the invention. It is formed from a single sheet of porbst filter paper, as described below.
. Den ovre ende 2 av posen er åpen, mens den nedre ende 3 er lukket. Den sentrale del av posen er i fig. 1 fjernet for å vise de langsgående folder k og 5 på begge sider av posen. Antall folder kan variere og velges i overensstemmelse med den tillatte . The upper end 2 of the bag is open, while the lower end 3 is closed. The central part of the bag is in fig. 1 removed to show the longitudinal folds k and 5 on both sides of the bag. The number of folds can vary and be chosen in accordance with the permitted
luftmotstand av den totale poseflate med hensyn til papirets luftgjennomtrehgelighet og dets egenskaper med hensyn til å kun-ne motstå ig.1 ent etnlng av fine stb vpartiwi sr air resistance of the total bag surface with regard to the air permeability of the paper and its properties with regard to being able to resist ig.1 ent etnlng of fine stb vpartiwi sr
Som det fremgår av fig. 1 er posens ovre, åpne ende 2 deformert ved at foldene er spredt ut for å danne en stort sett tilplat-tet endesone 6 rundt posens munning. As can be seen from fig. 1, the upper, open end 2 of the bag is deformed in that the folds are spread out to form a largely flattened end zone 6 around the mouth of the bag.
Det er onskelig at stovposen ved anvendelse ekspanderer, når posen gradvis fylles med stov o.l., idet foldene tillater en så-dan ekspansjon. På grunn av anordningen av foldene ved pose-bunnen 35som angitt ved 7»blir imidlertid ekspansjonen av foldene nær denne bunn begrenset, hvorved også ekspansjonen av den nedre del 8 av posen rent generelt begrenses. Fig. 2 viser det ytre kartongsjikt i form av en skive 9 med et sentralt, rundt hull lo og en flik 11 for manuell fjernelse av stovposen fra stovsugeren. Fig. 3 viser det indre kartongsjikt i form av en skive 12. Den har to fliker eller klaffer 13 og 1<*>+, hvilke er utformet i ett stykke med skiven og brettbare langs markerte linjer 15 resp. 16 og som er utskåret fra skiven 12 langs linjene 17, 18 og 19-De strekprikkede linjer 2o og 21 angir det areal innenfor hvil-ket den tilplattede endesone av papirposen klebes fast til un-dersiden av skiven 12 omkring hullet, som dannes når de to klaffer 13 og 1<1>+ bbyes innover til åpen stilling ved linjene 15 og 16. It is desirable that the dust bag expands during use, when the bag is gradually filled with dust etc., as the folds allow such an expansion. However, due to the arrangement of the folds at the bag bottom 35 as indicated at 7", the expansion of the folds near this bottom is limited, whereby the expansion of the lower part 8 of the bag is generally limited. Fig. 2 shows the outer cardboard layer in the form of a disc 9 with a central round hole and a flap 11 for manual removal of the dust bag from the vacuum cleaner. Fig. 3 shows the inner cardboard layer in the form of a disk 12. It has two tabs or flaps 13 and 1<*>+, which are formed in one piece with the disk and can be folded along marked lines 15 or 16 and which is cut out from the disc 12 along the lines 17, 18 and 19 - The dotted lines 2o and 21 indicate the area within which the flattened end zone of the paper bag is stuck to the underside of the disc 12 around the hole, which is formed when the two flaps 13 and 1<1>+ are bent inwards to the open position at lines 15 and 16.
Fig. h vi ser et planriss av hele posens skive med de stengte klaffer 13 og 1<*>+ synlige gjennom hullet lo. En trådfjær (jfr. også fig. 6-8) har en stort sett U-formet del 22 og to frie ender 23 og 2h. Den U-formede del 22 er fastklebet mellom de indre og y.tre sjikt 9 og 12, som angitt med strekede linjer, mens de to frie ender 23 og 2h rager ut og ligger an mot undersidene av klaffene 13 resp. lk når disse er i stengt stilling, som vist i fig. ' h. Når klaffene fores innad, overvinner de motstan-den av fjærendene 23 og 2*+, idet fjærene soker alltid å tilbake-fore klaffene til stengt stilling hvor posen er lukket. Fig. h we see a plan view of the entire bag disc with the closed flaps 13 and 1<*>+ visible through the hole lo. A wire spring (cf. also fig. 6-8) has a largely U-shaped part 22 and two free ends 23 and 2h. The U-shaped part 22 is glued between the inner and outer layers 9 and 12, as indicated by dashed lines, while the two free ends 23 and 2h protrude and rest against the undersides of the flaps 13 and 2h respectively. lk when these are in the closed position, as shown in fig. h. When the flaps are lined inwards, they overcome the resistance of the spring ends 23 and 2*+, as the springs always seek to return the flaps to the closed position where the bag is closed.
Av flg. 6-8 fremgår at den U-formede del "22 av fjæren er forenet med de frie ender 23 og 2k ved hjelp av mellomliggende partier : 25 resp. 26. Figurene viser at delene 23, 2h og 25, 26 er bby-et ut av den U-formede dels 22 plan, slik at delene 23 og 2h kan rage ut mellom kartongsjiktene 9 og 12 og ligge an mot klaffene 13 og l1*, som angitt i fig. k. From fig. 6-8 it appears that the U-shaped part "22 of the spring is united with the free ends 23 and 2k by means of intermediate parts: 25 and 26 respectively. The figures show that the parts 23, 2h and 25, 26 are bby -et out of the plane of the U-shaped part 22, so that the parts 23 and 2h can protrude between the cardboard layers 9 and 12 and rest against the flaps 13 and 11*, as indicated in Fig. k.
